eroticearth22nd: “Now this is the nipple which is surrounded by the areola, as I’m sure you’ve all seen plenty of. Both have different histology from the rest of the tissue on the breast and the nipple is where babies suck on to receive breast milk. Yes Angela?” “Nipples are different for men and women, right?” “Yes, that’s correct. While on men the nipple is vestigial, for women it is how we deliver our breast milk, which is mostly produced during and for some time after pregnancy. However, in both men and women, nipples and areolas are erogenous zones, as well the rest of the breast. Billy?” “Is it true that girls with bigger boobs are more sensitive?” “Actually the opposite is true. Breasts have a limited number of nerve endings so by having larger breasts you decrease the density of nerves and therefore make the breast less sensitive and require more stimulation. So while larger breasts are fun to play with, small breasts are much more sensitive. Remember that girls, all breasts have their advantages. Cynthia?” “Why are girl’s and boy’s breasts different?” “Because of the different hormones produced in each sex. Females produce high levels of estrogen which causes our breasts to become more pronounced due to added tissue and glands. Males produce very little estrogen, but produce a lot of androgen, which results in the male breasts being almost purely the pectoral muscle. Because of this, male breasts will only increase in size through exercise, while female breast size will increase naturally during puberty, however, sizes do vary. Nathan?” “Why do a lot of pornstars have really big boobs?” “Because they get surgical implants made of silicon, what most people call ‘boob-jobs.’ But as I’m sure you’re all aware, not all pornstars have fake boobs. Many prefer to remain natural, as do most women not in the adult industry.” “Are yours natural Ms. Peters?” “Yes they are. And relax, you can all put your hands down; after class you can all touch them.” -- source link
